‑ PM866K01 is full delivery kit, contains CPU board, TP830 baseplate, two bus terminators, backup battery and power plug, ready‑for‑DIN‑rail installation. Exchanges data with S800 I/O modules over internal CEX back‑plane bus. Single station can run one PM866K01 as standalone controller; two PM866K01 can build main‑standby redundant control system with RCU‑link cable, realize bumpless switchover upon main CPU fault.
‑ Supports IEC61131‑3 standard programming languages FBD, LD, ST, SFC. Completes complex continuous PID regulation, cascade control, split‑range control, safety interlock protection, sequential logic and large‑batch process control. Dual ethernet ports support network redundancy, connect 800xA operator station and engineering station. COM3 RS232 port used for modem connection; COM4 isolated RS232 port for local program download, debugging and third‑party serial device communication. CompactFlash card realizes program backup, restore and firmware upgrade. On‑board lithium battery keeps real‑time clock and retention process variables after power‑off. Dual‑level hardware watchdog realizes automatic reset when program runs abnormally.
‑ Module self‑diagnosis continuously monitors 24V power supply, CPU operation, memory fault, CEX bus and communication channel abnormality; fault codes and alarm messages are uploaded to 800xA operator workstation.
‑ Cannot run independently; kit already includes matched TP830 baseplate and accessories.
Difference compared with PM866AK01(3BSE076939R1): Same CPU hardware performance, different order article number, hardware mutually replaceable, need firmware version matching.Compare with PM864AK01‑eA：uses TP830 baseplate instead of TP850, supports CPU main‑standby redundancy, non‑SIL safety grade controller.
‑ Continuously monitors power supply, memory, CEX back‑plane bus and each communication channel status. Hardware fault will light front‑panel ERR fault LED and report fault alarm code to operator station.
‑ No local historical‑data storage; runtime status and fault diagnosis information are read via Control Builder M engineering tool.
‑ CPU hardware failure will lead to control station out‑of‑service; under redundant configuration, standby processor will automatically take over control task without production interruption.
‑ Back‑plane：CEX bus connector on TP830 baseplate, connect I/O bus and 24VDC power supply.
‑ External interfaces：dual RJ45 ethernet ports, COM3 RS232 port, COM4 isolated RS232 port, CompactFlash card slot, INIT reset button, RCU‑link redundancy interface.
‑ Mounting：DIN‑rail installation
‑ Operating Temperature：0 ℃ ~ +55 ℃
‑ Storage Temperature：‑40 ℃ ~ +70 ℃
‑ Relative Humidity：5‑95 %RH, non‑condensing
‑ Pollution degree：Degree 2
‑ Protection Class：IP20, cabinet‑internal installation.
- PM866K01 complete processor kit（3BSE050198R1）
Complementary parts: 24VDC power supply, S800 series I/O modules, CompactFlash memory card, RCU‑link cable( for redundancy), industrial shielded ethernet cables, Control Builder M engineering & 800xA monitoring software.
‑ Cut off power before inserting or replacing PM866K01 CPU module, hot‑swap function is not supported. Kit is pre‑equipped with TP830 baseplate, bus terminators and backup battery. When deploying redundant CPU, use special RCU‑link cable and follow redundancy configuration rules. Use industrial shielded cables for ethernet and serial wiring. Pay attention to lithium‑battery ageing, replace battery periodically to avoid loss of clock and retention data.
‑ For spare‑part replacement: verify full model PM866K01 and part‑number 3BSE050198R1; after hardware installation download firmware and user control program, verify logic operation, PID loop regulation and all communication channel data interaction. Pay attention to firmware compatibility when replacing with PM866AK01. Wrong baseplate or incompatible firmware version will cause station startup failure.
‑ Single CPU fault will result in control station stop; redundant configuration can avoid production interruption.
